Due to technological development in the globalized food system, quantitative problems of food supply have been solved, but food risks have expanded from problems in specific regions to global problems. In order to maximize the efficiency of agricultural production, the growth in agricultural production system, procirement of raw materials, establishment of food processing processes and establishment of food supply chain systems are required. Control of hazards requires facility and administrative efforts. In this study, we examined the role of CSR in conjunction with food safety. Food SCM is related to food safety and correlates with the food supply chain. In terms of the triple bottom line theory, CSR is correlated with SCM and it is possible to pursue food safety through corporate CSR and SCM. In this study, it is statistically confirmed that SCM and CSR are in a positive relationship. In the impact of CSR on food safety, it has been confirmed that economic responsibility and legal responsibility take precedence over environmental responsibility and social responsibility. Based on this, we can achieve food safety through SCM and CSR, and we can decide which of CSR activities can be prioritized.

This article analyzes issues regarding the economic development of the arctic area with the aim of finding ways to help solve the problems and to support sustainable economic development of the arctic area. Some proposals are introduced for establishing a sound legal infrastructure of the Korea-Russia economic development of the arctic area. As Russia develops the Arctic area and the route through the Arctic area, Korea will gain the possibility of transportation efficiency, vitalization of international transaction, and finding new markets. Resource development in the North Pole is ongoing, with matching international transaction and economic benefits. To reflect the Korea-Russia interests and to sustain the effect, the legal infrastructure is inevitable. For example, it would be reinforced by pushing forward the Korea-Russia FTA. The legal infrastructure for economic cooperation of Korea and Russia has to reflect that 'the development of the Arctic area and making the route through the Arctic area' should increase the sustainability and vitality of international transaction. The legal infrastructure for economic benefits can also help mitigating non-economic arguments of international community such as the security risk in the Korean-peninsula and around the world.

Purpose - The purpose of this study is to analyze the efficiency of retail businesses by dividing domestic retailers into discount stores, super supermarkets (SSMs), and department stores. It suggests retail-business investment strategies by using data environment analysis (DEA) to analyze how input elements such as store area, parking lot area, number of employees, and sales management expenses for the convenience of customers positively affect business performance measurements such as sales and visiting customers per day. Research Design, Data, and Methodology - The DEA model calculates a ratio of the weighted mean of various inputs to the weighted mean of various outputs and measures the efficiency of a specific decision making unit (DMU). The study included 19 companies (five discount store DMUs, ten SSM DMUs, and four department store DMUs). Because the business elements and sizes of retail store DMUs used in this analysis are different, average per-store input and output variables were used. Data were collected from "The Yearbook of Retail Industry in Korea (2012)." DEA analysis was used to determine differences in efficiency among discount stores, SSMs, and department stores in terms of the business elements of each retail business. It was also used to determine what business elements were excessively invested in by comparing and analyzing efficiency by business elements using SPSS software's ANOVA (Analysis of Variance). Results - The CCR and BCC efficiency analysis found that the efficiency of discount stores is low. We believe that the saturation state of discount stores is a major factor. The ANOVA analysis confirms the VRS hypothesis with a statistically significant difference among the three groups, based on an analysis confidence interval of 95%. CRS and SE were not found to be significantly different among the three groups. As for the post hoc test, which concretely shows differences by group, the Scheffe's multiple comparison analysis test found the average differences between group 1 (discount stores) and group 2 (SSM) to be statistically significant. Conclusions - The DEA efficiency analysis implies that investment in input elements, including store area, parking lot area, and sales management expenses, were excessive in the case of discount stores, while SSMs need to invest more in promotion activities such as gifts, events, and coupons for customer management. Department stores have found that small companies invest excessively in input elements. Department stores need to invest in differentiated shopping mall complexes. This study was limited in acquiring statistical data; various input variables which might have shown more secure customer management and promotional expenses could not be applied. As the study was limited in various aspects of the efficiency analyses because financial analyses of the companies and of causal relationships, including satisfaction and loyalty of visiting customers, were not done, these aspects will be examined in the next study.

아세안(ASEAN) 국가 총 컨테이너 처리량은 경제발전에 따라 계속해서 증가할 것으로 전망된다. 하지만, 증가하는 물동량 대비 아세안(ASEAN) 국가 대부분의 항만인프라는 아직 미비한 수준이다. 세계은행 보고서에 따르면 싱가포르와 말레이시아를 제외한 항만들은 항만인프라 순위에서 낮은 순위를 기록하고 있다. 아세안(ASEAN) 항만개발사업 참여는 아세안(ASEAN) 국가의 항만인프라를 개선하여 물류효율성을 증가시켜 우리나라와의 무역 활성화로 이어질 수 있다. 또한 우리나라 정부와 기업이 항만개발사업에 진출하여 우리나라 항만 관련 산업을 활성화시킬 수 있다. 항만효율성 측정은 이러한 항만개발 및 계획수립에 기초자료로 활용하기에 본 연구에서는 아세안(ASEAN) 항만 효율성 분석을 수행하였다. 본 연구에서는 여러 모형 중 가장 효율적인 DEA모형을 알 수 없다는 한계점을 극복하고자, DEA와 Shannon's Entropy를 결합한 모형을 활용하여 아세안(ASEAN) 항만의 효율성을 측정하였다. CCR, 투입기준 BCC, 산출기준 BCC, SBM 모형 등 네 개의 모형의 가중치를 구한 뒤에 가중치를 고려하여 항만별 효율성을 측정하였다. 결과적으로 세계 주요 항만인 싱가포르, 말레이시아 항만의 효율성이 가장 높은 것으로 나타났으며, 물동량 증가율이 가장 높은 베트남의 항만효율성은 상대적으로 낮은 것으로 나타나, 항만개발이 필요한 것으로 나타났다. 태국의 림차방(Leam Chabang), 베트남의 호치민(Ho Chi Minh City), 인도네시아 탄중 프리옥(Tanjung Priok)항만은 물동량 처리실적과 효율성이 역의 관계로 나타나 경쟁력 유지를 위해서는 효율성 개선이 필요 한 것으로 보인다. 캄보디아, 미얀마, 브루나이 등 아직 경제발전이 미숙한 항만은 경제발전을 위해서라도 인프라 확장을 위주로 하는 항만개발이 필요한 것으로 분석되었다.

Generally, cable-stayed bridges are both statically indeterminate structure with a high degree of redundancy and flexible structure. So it is very important to ensure precision control during both fabrication and construction. In precision control of cable-stayed bridges, precision control under multi-objective programming method is needed, because precision control problem of cable-stayed bridges is a multi-objective programming problem in which many objective functions are regard as variables. In previous studies, it was regarded as a single-objective problem, so it had many problems in respect of usefulness and rationalness. In this study, precision control under multi-objective programming method is proposed considering economy, efficiency, and safety at best in precision control of cable-stayed bridges. Precision control problem of cable-stayed bridges is formulated with satisfying trade-off method which is a kind of multi-objective programming method, then it is optimized with min-max method. A computer program is presented including above process.

This study firstly aims to review the discussions among major nations and international organizations on removal of tariff wall in EC. Secondly, it is analyzed how the trend of tariff reduction of removal will affect an individual economy in a partial balance analysis model on an assumed small-size economy. In closing, political implication for removal of tariffs in EC will be presented. The study concluded that tariff removal on Internet EC has both positive and negative effects on the importing economy. It can improve the efficiency in utilization of economic resources by the importing economy in the long term while cut the financial revenue and aggravate the trade balance of importing country. It is inferred from such a conclusion that tariff removal can lead to trade imbalance between the Information haves and the have-nots.

This study aims to present the effects of the introduction of the Compliance Program in Korea on real trade and its implication by empirical analysis. First, through regression analysis based on the data of the amount of permitted export by CP items (HSK10 units) during the period of 2010-2016 in Korea, it is revealed that the increase in export license of CP enterprises has a relatively greater effect on the increase in total imports by item. Second, since the introduction of the rating system under the optional CP in 2014, the increase in export licenses of CP companies has had a greater impact on the total export growth by items than before. Also, it is analyzed that the increase of export permission of CP companies has a relatively less effect on the increase of total imports by item than that of total exports. The results of this empirical analysis show that CP has a positive effect on exports and imports, but it needs to be supplemented in terms of efficiency.

The purpose of this paper is to examine whether the international electronic payment system through IDENTRUS can be active in the future or not. For this purpose, we have reviewed the various aspects of the typical systems : their types, operational mechanisms and actual limitations in real trade. Then we have proceeded to examine the distinguished features of IDENTRUS in terms of operational procedures and characteristics by comparing to other systems. Specially as the preconditions of activation, the possibilities of cost down, time reduction, risk hedging and operational efficiency have been studied. Thus we are not sure that the IDENTRUS will have a position as a main stream in the future electronic payment system, but this system would contribute positively to the establishment of electronic payment system if some functional additions will follow.
